The new ruling accuses Johnson of misleading the queen to act unlawfully when he asked her to sign off on prorogation. Although a London court ruled last week that the suspension was constitutional, Scottish judges reversed that decision.

Despite declaring the House of Commons’ recess “null and of no effect,” the Scottish court did not issue an injunction ordering Parliament to return to Westminster. The chief judge said the court would defer a decision that would force members of Parliament to come back to work. The U.K.’s Supreme Court will hear an appeal from the government next week.

Anti-Brexit politicians, including the more than 75 MPs who brought the case to the Scottish court, celebrated the decision. Scottish National Party (SNP) MP Joanna Cherry said that her side “feels utterly vindicated and confident.”

The government is facing further backlash over accusations of questioning the court’s impartiality after a Johnson ally told The Sun newspaper, “The legal activists choose the Scottish courts for a reason.”
